Title: Acoustic damper device
Inventor: MIYAGAWA HIDEKAZU
IPC: G10K11/178
Filed: 1987-10-21
Abstract: PURPOSE:To prevent a head and a recording medium from vibrating abnormally, in a magnetic recording apparatus having a damping device, by incorporating a sound wave projecting pipe for emitting sound waves integrally with a vibration sensor, and by providing a drive device for applying a damping signal to an acoustic speaker. CONSTITUTION:A gimbal spring 2 having three degrees of freedom is bonded at its peripheral edge to a movable arm or a carriage 1. A magnetic head 3 is fixed to the gimbal 2 at the center thereof. A vibration sensor is disposed in the outlet port of a sound projecting pipe 6 connected to an acoustic speaker 5. A drive device 8 in the acoustic speaker 5 is composed of amplifiers 81, 83 and a phase adjusting circuit 82 which delivers an output signal having a phase which is opposite to the phase of an input signal. Thus, sound waves having a phase opposite to the phase of vibration detected by the vibration sensor 7 are projected to the gimbal spring 2. With this arrangement, it is possible to prevent the head and a recording medium from vibrating abnormally.
